💧 Hamster Nephritis (Kidney Inflammation): A 2025 Guide by Dr Duncan Houston BVSc 🩺

By Dr Duncan Houston BVSc – Nephritis, or kidney inflammation, is a serious condition in hamsters—especially older or female pets—that often correlates with amyloidosis, hypertension, infection, or toxicity. In this comprehensive 2025 guide, we’ll explore symptoms, diagnostic tools, supportive treatments, and prevention strategies to help protect your hamster’s renal health. Let’s safeguard those tiny kidneys! 🐹

📘 What Is Nephritis?

Nephritis refers to inflammation of the kidneys, affecting structures like tubules, glomeruli, or interstitium. In hamsters, it may occur due to:

• An immune-related process (e.g., amyloid deposition ⌛)
• High blood pressure or toxins
• Chronic infections or immune-mediated damage
• Medication-induced injury (e.g., NSAIDs) possibly causing papillary necrosis :contentReference[oaicite:3]{index=3}

🧠 Why It Matters

Kidneys regulate fluid balance, filter toxins, and regulate electrolytes. Persistent inflammation or glomerular damage leads to proteinuria, dehydration, hypertension, and eventual kidney failure—often limiting lifespan in aging hamsters. Renal issues are common in hamsters over 1 year—especially females :contentReference[oaicite:4]{index=4}.

⚠️ Who Is at Risk?

• Older hamsters (especially females) with signs of amyloidosis and kidney damage :contentReference[oaicite:5]{index=5}
• Pets exposed to nephrotoxic medications like NSAIDs (e.g. mefenamic acid) :contentReference[oaicite:6]{index=6}
• Those with chronic infections, immune disorders, or hypertension
• Hamsters with amyloid deposition—often concurrent with renal inflammation :contentReference[oaicite:7]{index=7}

🩺 Clinical Signs to Watch

• 💧 Marked increase in drinking and urine output
• ➖ Gradual weight loss despite good appetite
• 🩸 Proteinuria—urine appears foamy
• 😔 Lethargy and rough coat
• 🫁 Labored breathing or edema—if fluid accumulates externally

🔍 Confirming Diagnosis

• 🔬 **Urinalysis** reveals proteinuria and decreased specific gravity
• 🧪 **Bloodwork** shows elevated BUN/creatinine and electrolyte disturbances
• 🩻 **Ultrasound/X-ray** can detect enlarged or shrunken kidneys; amyloid gives a granular, pale kidney appearance :contentReference[oaicite:8]{index=8}
• 🧬 **Biopsy**—definitive, albeit invasive—renal histopathology may show tubular damage, interstitial inflammation, fibrosis :contentReference[oaicite:9]{index=9}
• 🫀 **Blood pressure measurement** to detect hypertension

💉 Treatment & 2025 Supportive Care

1. Hydration & Fluid Management

• 💧 Encourage increased water intake
• 💉 Provide gentle subcutaneous fluids (e.g. 10–20 mL/100 g depending on hydration)

2. Diet & Electrolyte Balance

• 🍽 Low-protein, low-phosphorus renal diets to reduce kidney workload
• 🧂 Moderate salt restriction to manage blood pressure
• 🥦 Antioxidant supplements—e.g. omega-3s, quercetin—to minimize inflammation

3. Medical Therapies

• 🫀 **ACE inhibitors or amlodipine** to manage hypertension
• 🦠 **Antibiotics** for secondary infections after culture confirmation
• 💊 **Anti-inflammatory agents** like omega‑3 or low-dose corticosteroids—only if immune-mediated
• ⚠ Avoid nephrotoxins (e.g. NSAIDs, aminoglycosides)

4. Monitoring & Follow-Up

• 📅 Monthly monitoring of weight, water intake, urine output
• 🩸 Repeat blood/urine tests every 4–6 weeks to track progress
• 🩻 Ultrasound every few months to observe structural changes

🏠 Home & Quality-of-Life Support

• 🛏 Soft bedding and shallow water dishes for easy access
• 🌡 Warm, draft-free environment (~22‑24 °C)
• 📋 Keep a hydration/daily chart for vet review
• 🎯 Use litter boxes for easier urine monitoring
